Abstract
In a thread-wound golf ball comprising a thread-wound core and a cover, the cover is formed of a vulcanized rubber composition comprising a base rubber containing at least 30% by weight of transpolyisoprene and has a vulcanizing sulfur content ratio between radially outer and inner half regions of from 1/2 to 4/1. Sufficient vulcanizing sulfur available throughout the cover renders the cover to be resistant to cut and shear so that the ball becomes durable.
